I use a clean 4.1 install with Debian as default VM.
The copy and paste doesn’t work.
If I use CRTL Shift C, a popup of the clipboard is shown but shows that 0 bytes are copied to clipboard. My CTRL Shift V confirms this in a sense that nothing is shown.
Anyone has a clue why nothing is copied if I actually use the Qubes Clipboard function and also get a pop-up in the upper-right corner to confirm that this function is used.
